BACKGROUND

The present disclosure relates to the field of information processingtechnique, and more particularly, to an information processing methodand an electronic device.

In a Long Term Evolution-Advanced (LTE-A) mobile communication system,Small Cell is introduced in order to enhance the capacity of networkusers in a hot spot, increase the flexibility of network deployment, andmeanwhile improve the spectral utilization. Small Cell is quitedifferent from the previous concepts of Home eNB and Pico Cell: based onwhether a Small Cell can be independent of a Macro Cell, the Small Cellcan be divided into Standalone Small Cell and Non-standalone Small Cell,the Standalone Small Cell refers to that operation of the Small Cell canbe completely independent of a Macro Base Station, it is mainly to solvea coverage problem; whereas the Non-standalone Small Cell refers tooperation of the Small Cell must rely on a Macro Base Station, needs theMacro Base Station to schedule, it is mainly to share the Macro BaseStation's load. The Macro Base Station and the Small Cell adoptdifferent frequency bands or the same frequency band. For example, theSmall Cell usually adopts a frequency band of 3.5 GHz. Due to the smallcoverage of the Small Cell, deployment of the Small Cell is not asstrict as that of a Macro Cell. After the Small Cell is completelyturned on, co-frequency interference between the Small Cells or betweenthe Macro Cell and the Small Cell are very serious. Related measures arerequired to avoid such interference. However, currently, there are norelated techniques available for reference.

Hereinafter, substance of the technical solutions of the embodiments ofthe present disclosure will be further explained through specificexamples.

The embodiments of the present disclosure are applicable to theNon-standalone Small Cell controlled by a Base Station. After theNon-standalone Small Cell is deployed, Discovery RS (DRS) is introduced,the cycle of each DRS is 40 ms, its emergence position is distributed bya Macro Base Station in different 1 ms sub-frames based on a differentSmall Cell, the signal transmitted by the Small Cell may be divided intothree states as follows:

On-state: like a Macro Cell, transmitting conventional reference signalssuch as PSS, SSS, CRS and physical channels such as PBCH, PDCCH, andPDSCH; a protocol layer monitors a control command transmitted by theMacro Base Station through X2-C.

Off-state: the Small Cell does not transmit any signal under this state,meanwhile a protocol layer monitors a control command transmitted by theMacro Base Station through X2-C.

Dormant-state: the Small Cell only transmits the DRS signal periodicallyunder this state, without transmitting any conventional referencesignal, meanwhile a protocol layer monitors a control commandtransmitted by the Macro Base Station through X2-C.

A state shift of the Small Cell is controlled completely by the MacroBase Station, after the UC ends the RRC connection, it cannot reside inthe Non-standalone Small Cell.

When the Macro Base Station detects and finds out that the capability ofthe connected UE supports carrier aggregation, dual-link, or the load ofthe Macro Base Station enters a cardoon, then the Macro Base Stationturns on the Non-standalone Cell by the following steps.

1. The Macro Base Station controls the UE Small Cell that may be coveredby multiple subordinate signals to enter a Dormant state (if the SmallCell is in an On state, then it remains unchanged), meanwhile specifyingthe transmission power of the Small Cell, if is an already-turned-onSmall Cell, its transmission power remains unchanged.

2. The Macro Base Station transmits, through an RRC message, a serialnumber that specifies the Discovery RS signal of a sub-frame and asub-frame position of the signal to the UE, and notifies the UE toasynchronously measure the Discovery RS signal, after the UE completesthe measurement, it reports the measured RSRP to the Macro Base Station;meanwhile, the Macro Base Station notifies a relevant Small Cell toperform a co-frequency interference measurement, and reports themeasurement result to the Macro Base Station.

3. The Macro Base Station selects, based on RSRP measured by the UE onthe Discovery RS and the result of co-frequency interference measurementbetween Small Cells, several suitable Small Cells, standards for theselection are:

the signal strength of receiving Discovery RS (RSRP) measured by the UEis larger than −110 dBm and the strength of co-frequency interferencemeasured by the Small Cell is less than −150 dBm; a Small Cell thatsatisfies the aforesaid condition is called a suitable Small Cell.

4. If there is no Small Cell that satisfies the aforesaid condition, thetransmission power of the Small Cell that is in a dormant state ischanged (i.e., increasing the transmission power), until a suitableSmall Cell is selected; in this way, the transmission power of allcandidate Small Cells is specified, and will not change after beingturned on.

5. The Macro Base Station turns on the Small Cell that is in a dormantstate and is a suitable Small Cell, and turns off the non-suitable SmallCell that is not selected, thus the first stage of DRS signalmeasurement is completed.

6. The Macro Base Station notifies the UE to measure the RSRP of theCell-specific RS of the Small Cell that is turned on, and reports themeasurement report to the Macro Base Station; the Macro Base Stationselects one best Small Cell based on the following rule:

rule for the best Small Cell: the RSRP of the Cell-specific RS of theSmall Cell that is turned on is the largest.

7. Turning off the Small Cell that is not selected and switches from thedormant state to the On state during the first stage, only one bestSmall Cell is retained.

8. According to specific cases of the user: comprising the Macro BaseStation and the Small Cell will form a carrier aggregation, or form adual direction, or the Macro Base Station will switch to the Small Cell.The specific protocol process is exactly the same as that from a MacroCell to a Macro Cell.

9. After the UE ends the RRC connection, it cannot reside in the SmallCell, but must return and reside in the Macro Base Station. When all theUEs in the Small Cell end the RRC connection, the Macro Base Stationturns off the Small Cell.

As shown in FIG. 8, the UE and the Macro Base Station form a normal RRCconnection, when the Macro Base Station finds out that its load enters acordon, it needs to move the UE in a Small Cell, the Macro Base Stationjudges, based on the physical position of the UE, Small Cells 3, 4, 5may become a suitable Small Cell for the UE, Small Cells 3, 4, 5 all arein an Off state, Small Cell 1 is in an On state because of beingconnected by the other UE. A first stage of selection of a group ofsuitable Small Cell: Small Cells 3, 4, 5 enter a dormant state under theinstruction of the Macro Base Station and transmit the Discovery RSsignal, the UE measures the Discovery RS signal of Small Cells 3, 4, 5,meanwhile Small Cell 3, 4, 5 measure the co-frequency interference whichit is subjected to. The result is: the signal strength (RSRP) receivedby the UE is: Small Cell 3>Small Cell 4>Small Cell 5, but none of themexceeds −110 dBm, but since Small Cell 3 gets co-frequency interferencefrom Small Cell 1, and the interference strength exceeds −150 dBm, SmallCell 3 is excluded from being a suitable Small Cell, and therefore isturned off. In this way, Small Cells 4, 5 become a group of suitableSmall Cell. A second stage of selection of the best Small Cell: theMacro Base Station turns on Small Cells 4 and 5 completely, the UEmeasures the Cell-specific RS signal of Small Cells 4 and 5, to obtainthe most reliable reception signal strength, with a result as below:Small Cell 4>Small Cell 5. Finally, Small Cell 4 is selected as the bestSmall Cell, Small Cell 5 is turned off. The UE is switched to Small Cell4, which reduces the load of the Macro Base Station.
